Application filedlanuary 15, 1923. Serial No. 612,871.

To all whom it may concern Be it known that I, EUGEN' HAGENBUCHER,residing at Essen, Germany, a citizen of the German Republic, haveinvented a certaln new and useful Improvement in Locomotive Tenders, ofwhich the following is a specification.

This invention relates to locomotive-tend- I ers and has for its objectto provide a tender the frame of which forms Walls of a tank adapted toreceive at least part of the water to be carried by the tender.

The accompanying drawing illustrates, as an embodiment of thesubject-matter of the invention, a tender of a condensing locomotive.

Fig. 1 is a side elevation of the tender, partly in-section,

Fig. 2 a section on the line 2-2 of Fig. 1, seen from above, and

Fig. 3 a section on the line 33 of Fig. 1.

The frame of the tender which is supported by two trucks provided withwheels A, possesses beside the main sole bars, not shown in the drawing,two plate girders B which extend throughout the entire length of thetender. The plate girders B are erilarged downwardly in the middle andrigidly connected with each other by means of four [-shaped cross bars0' (see particularly Fig. 1). The enlarged portions of the longitudinalgirders B constitute 'the .two side walls of a tank D which is disposedbetween the two trucks A and designed to receive part ofthe Water to becarried by the tender. The tank D is narrowed at the two ends directedtowards the trucks A, in order to allow the tank to be extended betweenthe wheels of the trucks A up to the cross bars C which are situatednext to the tank D, see particularly Fig. 2. The side walls of thenarrowed tank portions are formed by plates E and their end walls by thecross bars G. The bottoms F of the narrow tank portions are inclinedand. rise towards the cross bars C. The cover of the tank D is formed bya horizontally arranged plate Gr which is connected by L-irons g withthe upper edges of the longitudinal bars B and cross bars G. .The tenderfurther carries on both ends of its frame each a Inserted in the watertank H which is in communication with the water tank D by a pipe J (Fig.1).

ipe J is a valve L controlled by afloat and designed to regulateautomatically the supply of the water from the tanks H into the tank Din such. a man-v ner'that the level-of the water in the tank D will bemaintained at a constant height as long as water is contained in thetanks H.

,The re-cooling plant M is mounted on the frame of the tender betweenthe water tanks H. Above one of the two water tanks H there is stillprovided a space N for receiving coals.

The described construction renders it possible to store a relativelylarge quantity of the water to be carried by the tender in and below theframe of the same. The greater part of the space on the top of thetender frame is thus kept free for the carryin of coal and the mountingof the re-cooling plant so that the tender may be made of a relativelyshort length. With tenders for condenszng locomotives the storing of thewater in and below the frame of the tender is even of particularimportance inasmuch as the water present underneath the re-cooler, thisbeing a relatively large quantity of water, may take part in there-cooling process. It is thus rendered possible at the starting of thelocomotive at which much'steam is consumed, to condense all of theexhaust steam without the circulating cooling water get- I tingexcessively heated.

In case all of the water carried by the tender should take-part in thecooling process, the whole 'of it has to be stored in the tank D; inthis case it will, however, be necessary to mount the frame B of thetender at a plane higher than usual.

I claim: ,7

1. In a locomotive tender, an under-frame comprising longitudinalgirders, wheeled trucks at either end of said girders for supportingsame, said girders each having adepending wall portion intermediate saidtrucks, transverse girders connecting said longitudinal girders, and abottom wall con necting the lower edges of said depending walls andtransverse girders for forming'a tank.

2. A locomotive-tender. comprising a frame, a tank having its wallformed by the vframe and adapted to receive part of the Water supply ofthe tender, water tanks 5 mounted on the frame of the tender, a pipeconnecting the Water tanks with the firstmentioned tank, a valveinserted in the said pipe and a float arranged in the first-mentionedtank and adapted to control the said valve.

The foregoing specification signed at Cologne, Germany, this 9th day ofDecember, 1922.
